2 Claims.

My invention relates to a furnace structure.

More particularly, my invention relates to an improved compact airheating furnace structur which may be resiliently mounted on thebuilding in which it is placed.

The present invention deals with an improvement on an air heatingfurnace structure disclosed in the copending application of Gleason etal., Serial No. 171,452, filed June 30, 1950. In the past, furnaces forbuildings have generally been shipped in parts and assembled at thelocation wher the installation is made. The furnace structure disclosedherein may be factory assembled, moved into the building as a unit andthereafter conveniently resiliently mounted on the building.

The principal object of my invention is to provide a furnace of the typedisclosed in the aforementioned copending application with improvedstructure for resiliently mounting the furnace within a building.

Another object of my invention is to provide an improved resilientmounting which may be conveniently utilized to mount an elongatedfurnace between the joists in the floor of a building.

Other objects and advantages of my invention will become more apparentfrom the following description taken in connection with the accompanyingdrawings in which:

Fig. 1 is a perspective view of a furnace illustrating the applicationof my invention thereto.

Fig. 2 is a plan view of the furnace showing the general arrangement ofparts therein.

Fig. 3 is a side elevational view of the structure shown in Figs. 1 and2.

Fig. 4 is a sectional view taken on the line 44 of Fig. 3.

Fig. 5 is a perspective view of the bracket assembly shown in Figs. 1 to4.

Fig. 6 is a sectional view similar to Fig. 3 showin a modification of myinvention.

Referring to the drawings, I have shown a furnace, generally designatedby the numeral [0, which is mounted between spaced longitudinallyextending joists, one of which is shown at l2. The mounting structures,generally designated by the numeral M, are disposed at four differentlocations and are adapted to support the furnace I0 relative to thejoists. Since all mounting structures M are identical, as shown in Figs.1 to 5, a description of on will suffice for all.

Referring now more particularly to Figs. 4 and 5, the mounting structurel4 comprises a gen- 2 erally U-shaped bracket l5 having outwardlyextending flanges 18 which are welded to U-shaped securin members 20.The members 20 are provided with openings 22 and 24 which receive nails26 and 28, respectively, the latter. serving to securely attach themembers 20 to the joist [2. The U-shaped bracket 16 is provided with abite portion 30 having a threaded centrally located opening 32 whichreceives a bolt 34 therein. The bolt 34 is provided with a head portion36 which is bonded to the lowerv surface of a cylindrical yieldablerubber-like cushion member The upper surface of the member 38 is bondedto the head portion 49 of the bolt 42, the latter extending through anopening M in a small leg 46 of an L-shaped bracket 48. The leg 46 isdisposed over the yieldable member 38 between the legs of the U-shapedbracket l6 and is provided with a long leg 5E3 which extends verticallydownwardly from the bracket l6 and is provided with an opening 52 at thelower end thereof. The opening 52 receives a bolt 54 which extendsthrough an opening 56 in the furnace Ill and is threaded into ananchoring member 58 which is securely fixed to the floor of the casingof the furnace. The openin 56 is provided with a rubber grommet fiilwhich lines the opening, cushions the leg iii] of the L-shaped bracket48 against the furnace as well as prevents the influx of any dirt withinthe casing of the furnace. The bolt 42 is provided with a nut 62 whichsecures the short leg 46 to the head portion ll] of the bolt 42. Thebolt 34 is provided with a lock nut 64 which not only may be tighteneddown on the underside of the bite portion 30 of the bracket [6 to lockthe bolt in place but also serves to fasten a cover member 66 in place.The cover member 66 is provided with a lower horizontal portion 68 whichhas an opening 10 through which the bolt 34 extends.

In Fig. 6 I have shown a modification of my invention wherein a U-shapedbracket 12 having legs 74 and 16 is secured to the joist I2 by nails I8and 80, respectively. The U-shapeid bracket 12 is provided with a biteportion 82 which is inclined clockwise approximately 20 as shown in Fig.6. This bite portion is provided with an opening 83 which receives a rod86 extending therethrough, one end of the rod being provided with anopening 88 which receives a bolt 90 extending from the furnace Ill. Anut 92 secures this end to the furnace. The other end of the rod 86receives a cylindrical yieldable rubber-like member 94 which is providedwith a centrally located opening 96 and is disposed around the rod at alocation between the legs 14 and 16 of the U-shaped bracket I2. Theextreme end of the rod 86 disposed within the bracket 12 is providedwith a circular disc 98 and nut I00 which serve to hold the assemblytogether, the weight of the furnace [0 being supplied through the rod"86 and disc '58 to the yiel'dable member 94 and hence to the bracket 32and joist I2.

In Figs. 1, 2 and 3, I have shown the furnace I 0 provided withoppositely disposed openings 62 and I04. The opening I02 allows theheated air to pass from the furnace while theopenirig w l receives thecold air returningto"the'iurnace. The

opening I82 is provided with a flexible coupling I06 which connects theopening to ducts [08,

while the opening I94 is connected by a flexible coupling III) to ductH2, The flexible couplings I06 and H0 are preferably made of fabricmaterial sii'ch as eanv'as or similar material and are accordionpleatedto facilitate installation as Well sis-flexibility. For the pur'pose ofillustration,-the duct I llfi-isconnected to'duct l- M andhot airregister-l ifi disposed in the wall fl3 WhiIG th'E CIUCt H2 is connectedto duct (20 and ccld airreturn register 422 disposed inthe wall i2 4,

It'wilLbe'seen fromthe drawi-ngs that the furtraceHl-is'completelyresiliently mounted relative to the joists; oneof-whichis-shoWn-at- [-2. The resilient mounting is supplied by I the mountingstructures -I i 'as- Well as the flexible connectors "36 and H0. By thisconstruction the vibrations caused-by the niovable parts disposed withinthe furnace l0 will-not b'e transferred to the joists. It will --also benoted thatby my improved construction of the=furnace ID, the furnace maybe conveniently placed between the joists and allow s'uflizintdiead-roomfor a normalsize person to walk beneath the furnace. Similarly, thisconstruction adds more usable space to the room in which it is locatedsince itis not mountedonthe floor of the room as most furnaces arebut itis rather-mounted in the ceiling of the room.

Wh-fl- I have illustrated" and described but two embodiments ofmyinvention, it'is-tobe understood that such is for=the purpose ofillustration only, and it is-oontemplated that those skilled in the artmay modify certain details without "deparing from the spirit or scope ofthe invention as defined in the claims appended hereto.
